Abstract

Oppfinnelsen tilveiebringer en fremgangsmåte til fremstilling av kitosan hvor prosessen omfatter å svelle partikkelformet kitin med en vandig løsning over en periode på minst 36 timer, og deretter reagere det resulterende svellede partikkelformede kitinet med en alkalisk løsning ved forhøyet temperatur hvorved deacetylering skjer.
